Title: EEPROM of NAND cell type - has memory cell transistors determining number of cell units with preset number of transistors in series
Inventor: OHUCHI KAZUNORI
IPC: G11C16/10
Filed: 1991-03-28
Abstract: Parallel data transmission lines are formed on a semiconductor substrate, intersecting with insulation parallel control gate lines and MIS FETs. The memory cell transistors determine a number of cell units, each with a preset number of series-connected memory cell transistors, coupled on one side to the respective data transmit lines, and on the second side to a source line. A data write unit (14,22,24,28) is coupled to the storage cell transistors for selective supply of a transistor gate electrode with a bias voltage of preset level, when a data program mode selects a memory cell transistor in one cell unit. Thus the electric data write condition of the selected transistor is verified or checked. USE/ADVANTAGE - Computer application with high operational reliability.

Title: Printing roller cleaning - uses laser beam to detach dirt and residue from surface without affecting surface character
Inventor: WAIZMANN FRANZ
IPC: B23K26/08
Filed: 1992-12-10
Abstract: The surface is cleaned by at least one laser beam directed at it, without altering the nature and character of the surface.The appts. with a laser beam system (2, 26, 36, 40, 42, 44) directs at least one laser beam (24, 46) at the surface (48) to be cleaned at the component (4).

The laser beam and the surface to be cleaned are moved in relation to each other at a speed of 0.5-1000.0 mm/s. During laser cleaning, the soiled surface is rotated and the laser beam is moved along the rotating axis at right angles to the beam direction, while the laser emitter is held at a constant gap from the surface being cleaned. The laser beam is pulsed against the component to be cleaned with a pulse repeat rate of 1 Hz to 1kHz with a pulse duration of 1ns to 5ms. An excimer laser is pref. with a computer control according to the operation of the printing press. USE/ADVANTAGE - The technique is especially for cleaning the surfaces of printing machine rollers, and the like, to remove residual ink or fibres or dirt and other matter. The action gives an effective cleaning operation, without damage to the soiled surfaces, in a simple system which occupies little space, and which has no effect on neighbouring components of the machine.
